Applecare™ PDS-300

• An all natural liquid, very easy to use in the color formulation development and in the manufacturing of the color products, especially for natural color cosmetics.
• Compatible with the oil blends containing up to 70% of Cyclopentasiloxane oil.
• Applecare PDS 300 can disperse the hydrophilic (non-surface treated) inorganic pigments (TiO2, ZnO, Iron oxide, etc) and fillers in the cosmetic oil into a low viscosity and high pigment load (up to 75% by weight) dispersion with common pigment dispersing equipments such as Cowles disperser, homogenizer, or propeller, etc. Additionally, it also changes their surfaces to become hydrophobic, improving their waterresistance and longer-lasting benefits. This unique combination of dispersing and surface-treating benefits make Applecare PDS 300 an essential ingredient in developing the new color control air cushion compact, which is a multi-tasking silky light CC foundation with broad spectrum SPF 50+, complete coverage, antiaging and deep skin hydration in an easy-to-use sponge package.
• Since it disperses and surface-treats the less expensive non-surface treated pigments at the same time to match up with the performances of the surface-treated pigments, it practically eliminates the need for the expensive surface-treated pigments. Applecare PDS 300 also works well for the surface-treated pigments, whose coating is not perfect.

Applecare PDS-300 is a COSMOS-approved advanced dispersing system for uncoated, hydrophilic color pigments, allowing formulators to disperse them into oil at eye-popping concentrations. 

This dispersing effect is so dramatic that formulators can use just a small amount of Applecare PDS-300 to reduce viscosity build-up in color cosmetic formulations with high amounts of pigment powder.  Internal loading tests have shown that using just 2.25% of Applecare PDS-300 can help disperse over 70% pigment grade titanium dioxide in capric/caprylic triglyceride, while still remaining very liquid and homogenous.

Furthermore, the switch from surface-treated pigments to uncoated pigments represents significant cost savings as well creating more flexibility in your supply chain.  

Control viscosity in natural color cosmetic formulations - 

Is your natural foundation too thick? Suffering from clumpy mascara? Applecare PDS-300 gives rheology control back to formulators, allowing them to reduce viscosity to their desired level by simply adjusting the amount of PDS-300 usage.

Clean and natural without compromising functionality - 

Applecare PDS-300 can create high quality fine pigment dispersions by smoothing out the average particle size as low as 2 microns, resulting in:
• Brighter Color Strength
• Increased Coverage
• Better Transparency and Opacity
• Boost Mattifying Properties
• Increased SPF Values in UV-grade Inorganic Pigments
• Smoother Sensorial Profile

Significantly increase pre-treated pigment performance -

not all pre-treatments result in perfect surface coverage, so Applecare PDS-300 can fill in the gaps to improve dispersing performance even more. 

Cosmetic and Toiletry:

• Beauty Products: foundation, mascara, lip products, pencils/liners, eye shadow, blush, etc.
• Color control air cushion compact - a low viscosity W/S-O foundation in a sponge package.
• Natural beauty products.
• Compressed or baked powder compact: Use as a liquid binder or part of liquid binders
• Sunscreen products with inorganic UV filters.

• Typical dosage is 5% by weight of the non-surface treated pigments, and is 2-3% for the surface-treated pigments.
• Processing to make a 70 – 75% pigment dispersion stock: 1). Mix the oil ingredients and the Applecare PDS 300 in a vessel at room temperature or preferable at > 65o C. 2) Add the pigment blend in 3 separate portions – 50%, 30%, and 20%, and mix each portion well at > 65o C until homogeneous before the addition of the next portion. And 3) if desired grind the dispersion further with ball mill or 3-roll mill to a finer dispersion.
• In-situ processing: 1) Mix a portion of the liquid oil components and Applecare PDS 300 together, so that the final pigment % is 40 % – 50%. Do not add the emulsifiers at this step. 2) Grind the pigments into the oil blend with homogenizer to a fine homogeneous dispersion, preferably at > 65o C. 3) you may incorporate the emulsifiers now and move to the next step in the O/W or W/O emulsion preparation.
